Relevant structure division of the present utility model at first sees also shown in Figure 1ly, and it mainly is to establish with two trailing wheels 11 at general motorcycle 10 tailstock, and constitutes supported at three points in ground with the front-wheel 12 of motorcycle 10 headstocks, can make the center of gravity of motorcycle 10 more stable.

Again motorcycle 10 be drive mechanism 13 with its tailstock via a changement 20 to drive two trailing wheels 11, detailed construction as for this changement 20, see also shown in Figure 2ly, it includes a selector 30, one is located at the gear 21 on the selector 30, one is located on the selector 30 and is positioned at the sprocket wheel 22 in aforesaid gears 21 outsides, one is located at selector 30 inner casing 23 of end in addition, one is located at the outer cage 24 in selector 30 outsides, (seeing also shown in Figure 3), two be individually fixed in, outer cage 23, hollow beam barrel 25 on 24, one pivot is through at the trailing wheel axostylus axostyle 26 of two beam barrels 25 etc.; Aforementioned changement 20 is to utilize a watchcase that it is coated fully, and is isolated from the outside.

As shown in Figure 2, this selector 30 is to be formed with an axial channel 32 on a hollow cylinder 31, cylindrical shell 31 1 ends are run through in this duct 32, be equipped with a moving rod 33 therebetween, cylindrical shell 31 periphery walls are formed with respectively in the equal angles place and radially run through barrel again, and be communicated with duct 32 wear groove 34, in present embodiment, this cylindrical shell 31 is formed with four groups and wears groove 34, and is the equal angles relation of 90 degree.

Moving rod 33 is positioned at cylindrical shell 31 1 ends and sets up several separately with equiangularly arranged and by radially outstanding raised line 330 again, and each raised line 330 is corresponding respectively to pass and respectively wear groove 34 on the cylindrical shell 31.

Cylindrical shell 31 outboard end appropriate locations are formed with an annular groove 310 again, and cylindrical shell 31 medial extremitys are formed with a jack-post 311 in addition, in order to link with aforementioned drive mechanism 13.

Be formed with axial trepanning 210 on this gear 21, for being sheathed on the cylindrical shell 31 of selector 30, trepanning 210 peritremes are formed with recess 211 respectively at the equal angles place again, and each recess 211 is the raised lines 330 that correspond respectively to moving rod 33.

Be formed with axial trepanning 220 on this sprocket wheel 22, for being sheathed on the cylindrical shell 31 of selector 30, trepanning 220 peritremes are formed with recess 221 respectively in the equal angles place again, and each recess 221 is the raised lines 330 that correspond respectively to moving rod 33.

On the cylindrical shell 31 of this selector 30 respectively behind sheathed gear 21, the sprocket wheel 22, sheathed again one places restrictions on ring 27, establishes C shape ring 312 subsequently on the annular groove 310 of cylindrical shell 31 outboard ends again, and with gear 21, sprocket wheel 22 and place restrictions on ring 27 and be fixed on the cylindrical shell 31.

Be arranged with a driven gear 28 and on this trailing wheel axostylus axostyle 26 by movable sprocket 29, wherein driven gear 28 be with selector 30 on gear 21 engagement, be to constitute interlocks (as shown in Figure 3) by movable sprocket 29 again by chain 290 and sprocket wheel 22 on the selector 30.

Moreover, with reference to shown in Figure 3, selector 30 is being hubbed on the outer cage 24 than miner diameter end with cylindrical shell 31 outsides, its moving rod 33 outboard ends are arranged with a spring 331, and be arranged with a baffle ring 332 in the outboard end place, and make spring 331 between 332 of cylindrical shell 31 and baffle rings, under general state, utilize the elasticity that supports of spring 331 that moving rod 33 is outwards pulled out, and the raised line 330 that makes moving rod 33 medial extremitys snaps in the recess 221 of sprocket wheel 22, when the drive mechanism 13 of motorcycle 10 drives selector 30 rotations, will drive sprocket wheel 22 simultaneously, and drive trailing wheel axostylus axostyle 26 via chain 290 by sprocket wheel 22, make two trailing wheels 11 do the forward running.

The commutation of steering mechanism 20 action is to cooperate a braking member 40 to reach by selector 30 again, as shown in Figure 3, this braking member 40 mainly is to be pivoted with a depression bar 41 on the beam barrel 25 on the contiguous outer cage 24, this depression bar 41 end in addition is provided with a boss grain 42, and corresponding supporting pulled in moving rod 33 outboard end, and depression bar 41 is provided with a backguy 43 in the end in addition, and backguy 43 is to pass outer cage 24, and be pulled to Che Shouchu, control by the driver.

As shown in Figure 4, when the driver spurs backguy 43, to make depression bar 43 is that fulcrum is swing counterclockwise with an end articulated section, and makes the boss grain 42 inside pushing moving rods 33 of end in addition, contracts in the moving rod 33 this moment, and make the raised line 330 of its medial extremity retreat in the recess 211 of gear 21 by sprocket wheel 22, under this state, gear 21 will utilize with trailing wheel axostylus axostyle 26 on driven gear 28 meshing relations, make two trailing wheels 11 be reverse running, change speech, this moment, this motorcycle 10 promptly was in a reversing state.

See also shown in Figure 5ly again, the outer cage 24 of this drive mechanism 13 and changement 20 is connected to chair base rear end with a buffering and shock preventing device 50 respectively, except that in order to fixed conveyor mechanism 13 and the changement 20, also provides a shock-absorbing cushioning effect.

Can set up a cross bar (not shown) separately on two beam barrels 25 again, cross bar in addition end is to be connected on the vehicle frame, with further fixedly beam barrel 25 and on changement 20.

Moreover, the syntagmatic of this changement 20 and two trailing wheels 11, can be only be connected with trailing wheel axostylus axostyle 26 by a trailing wheel 11 wherein, 11 of another trailing wheels are hubbed on its corresponding beam barrel 25, particularly, one of them tool power only in two trailing wheels 11, another then is a driven pulley, can obtain preferable stability whereby when motorcycle 10 is turned.

Can find out concrete structure kenel of the present utility model and basic functional principle by above-mentioned explanation, below further specify this utility model and utilize changement 20 to reach the working method of reversing purpose:

Before the driver does not spur the backguy 43 of braking member 40, moving rod 33 on the selector 30 is drawn outward by spring 331 elastic force, and make its raised line 330 correspondences snap in sprocket wheel 22, when selector 30 is driven by drive mechanism 13, to drive sprocket wheel 22 simultaneously, and drive trailing wheel axostylus axostyle 26 via chain 290, and make two trailing wheels 11 do the forward running, this moment, motorcycle 10 was to be in travel condition forward.

Spur the backguy 43 of braking member 40 as the driver, then depression bar 41 will push in the moving rod 33 and contract, and compress spring 331 on it, at this moment, the raised line 330 of moving rod 33 medial extremitys retreats to gear 21 places by sprocket wheel 22, makes selector 30 and gear 21 constitute interlocks, and this moment, trailing wheel axostylus axostyle 26 utilized the meshing relation of driven gear 28 and gear 21 it on, be the reverse running opposite with selector 33, this moment, motorcycle 10 promptly was in the reversing state.
